Answer:
b. 10.426%
Explanation:
Using the attached formula, convert the nominal rate to effective annual rate
m in the formula is the number of compounding periods per year; 12/2 = 6 in this case.
APR is the nominal rate which is 10%.
Next, plug in the numbers to the formula as shown below;
EAR = [tex][1+\frac{0.10}{6}]^{6} -1[/tex]
EAR = 1.10426-1
EAR = 0.10426 or 10.426% as a percentage
Hence choice B is correct.
